Determined Soul

Your soul refuses to die. You gain the following benefits:

• You have advantage on death saving throws.
• If a spell, such as raise dead, has the sole effect of restoring you to life (but not undeath), the caster doesn't need material components to cast the spell on you.
• When you drop to 0 hit points, your soul calls out for help. Up to five creatures of your choice that you have met before instantly know that you dropped to 0 hit points and know the direction and distance to you from their current location.
